GMC 1500 Sierra P/U Replaced fuel pump ( that originally was bad) and fuel filter but within a week it wouldn't start, or would quit after starting and now won't start unless I dump a touch of fuel directly into the engine.

I got a truck that is a 1994 GMC Sierra 1500 4x4. I replaced the distributor cap rotator cup and coil. After that its still losing power worse than it was before i bought the parts. What could be wrong


ever change the fuel filter???? a weak fuel pump can also give this effect.
they can give enuff fuel to run injectors but lack volume for sustained running at speed . try fuel filter first

I would lean towards the fuel pump, but... How dirty was the old filter??? if it was bad then the new one may have picked up whatever was left in the line. I guess I would go the easy route, replace the fuel filter, this time with the filter off crank the truck and catch the fuel in a mason jar til it is clean, you may need to drain the tank and try to clean it out if it is real dirty. Hope this helped Tim
